Techopedia Explains iPhone

The first iPhone was the result of a collaborative project between Apple and AT&T Mobility (known as Cingular Wireless at that time). Both the hardware and software portions of the phone was developed by Apple. The iPhone’s Unix-like operating system, iOS, is based on Mac OS X, the operating system that runs on Apple desktops and laptops.

Applications for the iPhone can be developed using the downloadable SDK (software development kit), which includes tools for developing, testing, running, debugging and tuning applications. Code can be edited, compiled and debugged using the Xcode tools. Xcode also allows developers to test apps either on an iOS device or an iOS Simulator.
